Engineers use a method in making important things like Computer chips or Solar panels; and it is called sputtering. This approach is particularly unique in that it leverages small particles called ions. These ions act as little messengers, which in turn hit atoms out of a target made from the material. After those atoms are removed they do not simply float absent. They just stick to everywhere where the engineers are working. This way, engineers have fine-tuned control over where every single atom goes in order to create a configuration that works just right.

​

Though, it is not easy to make a perfect target. One of the most difficult is guaranteeing that the target has not been contaminated. And what is it to be “pure” in this instance? That means target should not have any other materials with in it. If other materials are present, the ions could inadvertently pluck those atoms off rather than just removing the ones engineers had in mind. For this reason, engineers must be extremely careful and precise about setting sputtering targets. To make this real, they frequently leverage a process called "powder metallurgy. Like baking a cake, but with metal powder instead of flour. The metal powder is pressed together and heated until it becomes molten, upon which the particles stick to one another. And even if only a small percentage of the wrong material gets mixed in, it can spoil the whole target and make it valueless to them.

Cracks may appear when fitting targets, too – another major challenge to overcome for the engineers. If the targeted molecules get too hot, or are contacted by some undesirable gasses — cracking occurs. The concerning part of the game: if a target breaks then it cannot be used anymore. Developers will be forced to figure out how for instance, targets that do not break under weight can be created in a way which is also economically feasible metal sputtering targets. For example, Filtering processes (for those same reasons) can also be moved upstream in the process using a different material. They could try to deform the shape of target. For instance, target to draw rectangle may be easier if it is modified into a square (or another shape that stands stronger than the former).

Another concern that engineers must address is related to consistency; the target should wear uniformly as time passes. These beams of particularly high-energy ions bombard the target, forming little holes (or pits). The target begins to reduce in size, as these pits grow over time. The uneven distribution of wear and tear on the target can produce an inconsistent surface. On the contrary, it can be rough or re-mixed in areas that should not. Engineers have a few tricks up their sleeve to make sure the wear is even. There are other ways to move ions around; one involves the use of a magnet. This method of operation ensures the deposition onto parts which have not yet been worn away have a greater incidence ions hit it. Another way engineers secure bolts is by using a spinning system. As a result, the target rotates and ions of all types must go through each part equally while spin around in this system to keep an etched face even.

That also means, another important thing to get right is that the atoms come off of target. Occasionally, a target may be rich in one type of atom and short in another. You can also add more materials to the target, so engineers do this. Those extra materials do react with the unrequited atoms and make them become something else that is not a problem. So only the atoms that it wants will get released from this so called target to ensure at a molecular level, what comes of is right.

And then, of course the blanket will be subject to thermal stress. This is what happens when a target heats up and expands. After which, when it cools down further — contracting again. If this happens to many times the stone can forsake it because increases in temperature weaken each crystal and then when they cool off, they expand erratically. Even if the target is a material that should be heat resistant, this issue can still happen. But engineers need to be very careful with how quickly they heat and cool the ceramic sputtering targets in order to make sure this doesn't happen. They could also place their target on top of another protective layer if they wish to preserve it from temperature-related wear as well.

Finally, sputtering targets might appear a minor part of the bigger picture is concerned about when engineers are producing crucial stuff like computer chips or solar panels. This is why aspects people see as minor details are in fact vital for these technologies to succeed. There is a lot of hard work by and creativity from our engineers going into meeting these targets, to make sure everything ends up functioning as planned.
